[lwip-devel] [bug #19167] tcp timeout handler can cause crash being invoked by sys_sem_wait()

[Simon Goldschmidt]

Follow-up Comment #27, bug #19167 (project lwip):

Regarding the timestamps: I just realized there is a function sys_jiffies()
(defined in sys.h, should be included in sys_arch.c), which is extgensively
used in PPP.

So lwIP already needs a tick count or timer of some sort (if only for PPP).
Introducing timestamps for timeouts only should add a function like
jiffies_to_ms() to work (and the implementation of sys_jiffies() for those
who don't have it now).
